The Working of an atomizer depends upon

Options

A. Pascal's law
B. Bernoulli's theorem
C. Archimedes principle
D. Boyle's law

Answer

**Step-by-Step Solution:**

1. **Understanding the Atomizer:**
An atomizer is a device used to spray liquid, commonly found in perfumes and other liquid products. It operates based on the principles of fluid dynamics.

2. **Principle of Air Flow and Suction:**
The working of an atomizer relies on the principle of air flow and suction. When air flows through a horizontal pipe, it creates a pressure difference.

3. **Setup of the Atomizer:**
Imagine a horizontal pipe that passes over a vertical tube. When the piston in the atomizer is pushed in, it creates a change in pressure.

4. **Creation of Pressure Difference:**
As the piston is pushed, the pressure inside the horizontal pipe decreases. This decrease in pressure leads to suction in the vertical tube.

5. **Liquid Movement:**
Due to the suction created by the pressure difference, the liquid from the vertical tube is pulled up into the horizontal pipe.

6. **Application of Bernoulli's Theorem:**
The working of the atomizer can be explained using Bernoulli's theorem, which states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure. As the velocity of the air increases in the horizontal pipe, the pressure decreases, allowing the liquid to be drawn up and sprayed.

7. **Conclusion:**
Therefore, the working of an atomizer depends on the principles of air flow and suction, as well as Bernoulli's theorem.
